# std::experimental::filesystem::path::remove_filename

From cppreference.com
< cpp‎ | experimental‎ | fs‎ | path

path& remove_filename() | (1) | (filesystem TS)

Removes a single filename component.

The behavior is undefined if the path has no filename component (`has_filename` returns false).

### Parameters

(none)

### Return value

*this

### Exceptions

May throw implementation-defined exceptions.

### Example

Run this code

    #include <experimental/filesystem>
    #include <iostream>
    namespace fs = std::experimental::filesystem;

    int main()
    {
        std::cout << fs::path("/foo").remove_filename() << '\n'
                  << fs::path("/").remove_filename() << '\n';
    }

Output:

    "/"
    ""
